Problems solved by technology

[0004]The water-based inorganic zinc-rich paint currently on the market has strict requirements on the construction environment and supporting coatings. If it is larger than 80μm, it needs to be sprayed for 3 to 4 times, otherwise it is easy to cause cracks; and the flexibility, adhesion, heat resistance (average high temperature resistance 400 ℃), impact strength, salt spray resistance, heat and humidity resistance, weather resistance, etc. have yet to be determined. improve

Embodiment Construction

[0037] The specific implementation of the present invention will be described below in conjunction with the examples.

[0038] See Table 1 for the components and contents of the water-based inorganic zinc-rich paints in Examples 1-4.

[0039]

[0040] Table 1

[0041]

[0042] The preparation technology of water-based inorganic zinc-rich paint in embodiment 1~4 is as follows:

[0043] Weigh the ingredients contained in component A according to Table 1, firstly mix 500 mesh, 800 mesh, 1250 mesh spherical or flaky zinc powder, rare earth nano ceria and 800 mesh talc powder with a mixer and mix them evenly 20 min, the speed of the mixer is 40-150 rpm, and the A component is obtained.

[0044] Weigh the ingredients contained in component B as shown in Table 1, first fully stir potassium silicate and lithium silicate with a mixer for 20 minutes, and the speed of the mixer is 400-500 rpm; then slowly add potassium titanate whiskers to the above in the mixture,

Abstract

The invention provides an aqueous inorganic zinc rich paint, which is prepared by mixing a component A with a component B according to a weight ratio of 4:1, wherein the component A comprises 30-32% of 500-mesh spherical / flaky zinc powder, 30-32% of 800-mesh spherical / flaky zinc powder, 30-32% of 1250-mesh spherical / flaky zinc powder, 6-8% of nanometer cerium dioxide and 2-4% of 800-mesh talcum powder; and the component B comprises 38-50% of potassium silicate, 10-20% of lithium silicate, 8-10% of potassium titanate whiskers, 5-12% of aqueous self-drying organic silicon modified acrylic resin, 0.2-0.5% of defoaming agent, 0.5-1% of wetting agent and 12-20% of water. The aqueous inorganic zinc rich paint provided by the invention has the characteristics of excellent corrosion resistance, physical and mechanical properties, wet resistance, high temperature resistance and strong construction adaptability.

Description

technical field [0001] The invention belongs to the technical field of coatings, in particular to water-based inorganic silicate zinc-rich paints. Background technique [0002] Most of the metal components are made of carbon steel, manganese steel, cast steel and other materials, and they will be corroded to varying degrees in the environment of alternating dry and wet, sunlight exposure, high-speed water flow, salt spray, water medium, and microbial adhesion for a long time. One of the most commonly used anticorrosion and antirust methods for metal components is to coat the surface with anticorrosion paint to isolate the corrosive medium from the metal substrate. [0003] Traditional anti-corrosion paints are organic solvent-based paints, such as epoxy resins, polyurethanes, etc., which are not only toxic, odorous, and flammable, but also pose potential safety hazards during storage and transportation, and are likely to pollute the environment. Since the mid-1980s in Chin...
